ROLLER SKATE.

Application filed June 16, 1924. Serial No. 720,316.

To all whom it may concern:

Be it known that I, MICHAEL N. MATVEY- EFF, citizen of Russia, andresident of New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in.Roller Skates, of which the following is a specification.

My invention relates to roller skates and has a particular reference toskates employing two wheels for each foot.

The object of my invention is to provide roller skates which can beadjusted for different sizes of feet, and which can be made higher orlower according to the preference of the user of the skates.

)Vith ordinary skates it is necessary to manufacture a large variety ofdifferent,

sizes, also a variety of shapes for different feet; with my skates,however, only one size can be manufactured, and it can be then adjustedin length for different feet. The wheels can be also made higher orlower.

My invention is more fully described in the accompanying specificationand drawing in which Fig. 1 is a side elevation of my skate, Fig. 2 is aplan view of same, and Fig. 3 is a partial elevation of the skate showninFig. 1

with the wheels lowered.

My skate consists of a frame composed of a front portion 1 and a rearplate 2, connected together with bolts 3. The holes for the bolts arespaced equally apart, and additional holes 4 are provided in thealignment with the bolts'S, so that the skate can be made longer orshorter by connecting the frame parts 1 and 2 with different bolt holes.The rear portion 2 has a heel rest 5 attached on top with angles orbrackets 6 riveted to the frame part 2. The heel rest is made in theform of a box with ears 7 for a strap 8 which is used for fastening theskaters foot around the instep of the shoe 9.

The front plates of the frame are provided with lugs or angles 10supporting a foot plate 12. It is provided with a shoe clamp of anordinary construction and consisting of hooks 14 which can slide inguides 15 under action of a screw '16 with a square head 17 adapted tobe operated by a special key (not shown).

The front and rear end of the frame are provided with. pivots or bolts18 supporting wheel brackets 19. Each bracket consists of two platesembracing the wheels 20 and bolt position, Fig. 5 (high skate).

ed to the Wheel axles 21. The axles 21 are placed inside of the wheelbearings 22 which may be of any ordinary type.

The brackets 19 can swing around the pivots 18 between the horizontalposition, as shown in Fig. 1 (low skate) and an angular In each of thesepositions the bracket can be locked by means of locking bolts 23 passingthrough holes 2% in the frame and through one of the series of holes 25in the brackets, these holes 25 being arranged on an arc of a circle,the center of which lies in the center of the pivot 18.

Important advantages of my skates are that they can be adjusted fordifferent feet, can be adjusted as to their height, are simple inconstruction, consisting of simple stampings, and develop very littlefriction, allow-.
